GTX 285 equals GTX 580 in memory bandwidth

post #1 of 5
Thread Starter 
I've got my hands on a second hand EVGA GTX 285 and decided to see how far I could push it. Here are the results after an 8 hour session with Unigine Heaven 2.5:

Core: 648 --> 710
Shader 1476 --> 1550 (Didn't really play with this)
Memory: 1242 --> 1520!!! (3040 MHz effective)

I was suprised to see how ridiculously the memory overclocked.

It's GDDR 3 and running at 512-bit so you end up with 194.56 Gb/s of bandwidth, which is more than a stock GTX 580 (192.4 Gb/s).

If only this card had GDDR 5... drum.gif

Not to mention the stock 285's texture fill rate is 1billion/sec higher with less than half the cores..

512 bit bus is really expensive. there is a reason thin bus+ fast memory is preferred in today's cards
